This study used the Energy Dispersive X-Ray Fluorescence (EDXRF) spectrometry to determine the elemental composition of nineteen rock samples from the Pouma sub-division of Cameroon. The major chemical elements found in these samples were compounds of SiO 2 , Al 2 O 3 , K 2 O, Fe 2 O 3 , CaO, and P 2 O 5 . The elemental characterization of the investigated samples was used to evaluate the mass attenuation coefficients of the quartzite rocks using the XCOM analytical calculation software and the GEANT4 Monte Carlo computational toolkit. The mass attenuation coefficients were calculated for the average concentration values of the samples from different sampling sites. The mass attenuation coefficients generated using the GEANT4 simulation have uncertainties less than 4% in all the four investigated sampling sites compared to the analytical results. The results of the simulation showed that the calculated mass attenuation coefficients are in good agreement with the theoretical data. Therefore, the developed GEANT4 code for radiation properties assessment of rocks is accurate and could be used by scientists worldwide. The determination of these mass attenuation coefficients is consequently the unveiling of radiation shielding properties of the investigated material.
